The Nearby Supernova Factory reports that a spectrum (range 340-1000 nm) of SN 2005be (IAUC #8506), obtained April 6.49 UT with the SuperNova Integral Field Spectrograph on the University of Hawaii 2.2-m telescope, shows it to be a Type Ia about a week after maximum. It is quite similar to the spectrum of SN 1996X at that epoch [Salvo et al. (2001), through the SUSPECT database]. The supernova expansion velocity, derived from the minimum of Si II (rest 635.5 nm) and adopting the NED redshift of 0.03351 for the host, is 10,500 km/s.
